DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0051] The pack 10 in question serves to receive cigarettes as pack contents. A group of cigarettes 11 formed from a plurality of cigarettes arranged in formation fills the interior of a partial pack, in particular an inner pack 12. This is designed as a tight pack.

[0052] The cigarettes are arranged without additional inner wrapping, that is to say directly in the inner pack 12. The cuboidal inner pack 12 itself constitutes the contents of an outer pack 13, in this case in the embodiment of a classical tab box or hinge/lid pack.

[0053] The outer pack 13 in all three depicted illustrative embodiments is designed identically in the form of a tab box or hinge/lid pack and consists in a manner known per se of a (lower) box part 14 and a lid 15. This is connected integrally to the box part 14 by means of a transverse line hinge 16.

[0054] The box part 14 consists of a box front wall 17, a box bottom wall 18 and a box rear wall 19. External box lateral tabs 20 are positioned on both sides of the box front wall 17, and internally located box lateral tabs 21 are positioned on the box rear wall 19. These together form box lateral walls 22, in particular as a consequence of covering and connection (glue 87) to one another.

[0055] The lid 15 consists of a lid rear wall 23, an upper lid end wall 24 and a lid front wall 25 adjoining the box rear wall 19. Lid lateral tabs 26, 27 are arranged laterally on a lid rear wall 23 and a lid front wall 25 in order to form lid lateral walls 28.

[0056] A lid inner tab 29, which is folded against the inner side of the lid front wall 25 and is connected to the latter by adhesive bonding, for example by means of glue points, adjoins a free edge of the lid front wall 25.

[0057] Corner tabs, in particular bottom corner tabs and lid corner tabs, are arranged on the (inner) box lateral tabs 21 and corresponding to the (inner) lid lateral tabs 26. These are capable of being folded against the inner side of the box bottom wall 18 and the lid end wall 24.

[0058] As in the case of suchlike packs, an appropriate blank 30 for the outer pack 13 can usually be made of (thin) cardboard or an equivalent packaging material with appropriate or greater dimensional stability.

[0059] The inner pack 12 and its blank 33 (FIG. 6) are designed in a particular manner. The blank 33 for this purpose is likewise made of (thin) cardboard with a coating on one or both sides. The coating is designed in such a way that the packaging material as a whole is moisture-proof or aroma-proof. In particular the coating consists of plastic and/or a varnish layer and/or a metallic or metallized layer. The cardboard is coated preferably on only one external side. This solution offers a number of advantages. The cardboard is thus able to serve as a storage means for moisture and, for example, either to protect the pack contents from drying out or alternatively to absorb high moisture from the environment, in order thereby to prevent the pack contents from becoming too damp. In addition, the exchange of moisture and/or flavoring agents between the pack and the environment is restricted by the coating. On the whole, a comparatively moisture-proof and aroma-proof pack 10 results in this way.

[0060] The inner pack 12 forms a closed, cuboidal container for the group of cigarettes 11. For the withdrawal of the pack contents, that is to say the cigarettes, an access opening 35 is formed, which extends in the region of an inner front wall 36 and at least in the region of an adjoining inner end wall 37 of the inner pack 12.

[0061] The access opening 35 is designed in the case in question by the positioning of a punching in the material of the blank 33 for the inner pack 12. The material removed by punching can be either removed completely as waste or folded against the blank 33. In the latter case, the punching cut is not performed continuously around the access opening 35, but only partially, so that a residual connection remains, about which the material removed by punching can be folded against the blank 33. The material is preferably removed by punching, in this case folded against the inner side of the blank 33, so that it is not visible to the consumer.

[0062] The access opening 35 is covered by a re-usable actuating device, in particular by a closure label 42 configured as a tape. This consists of a foil and is provided with adhesive on the side (underside) facing towards the inner pack 12.

[0063] In the case in question, the underside of the closure label 42 is divided into three zones. A strongly adhesive adhesive, which serves for the permanent connection of the closure label 42 to the inner pack 12 in the region of the inner end wall 36 and an inner rear wall 39 of the inner pack 12 is provided in a first zone 38. The first zone 38 begins at an upper edge of the closure label 42 and extends more or less as far as the upper edge of the access opening 35. A strongly adhesive adhesive, which allows repeated actuation of the closure label 42, is provided in a second zone 40, which adjoins the first zone 38 and extends around the access opening 35 in a U-shaped manner and ends shortly beneath a lower edge of the access opening 35. In a third zone 41, which adjoins the second zone 40 and extends continuously as far as the lower edge of the closure label 42, no adhesive is provided on the underside of the closure label 42. Accordingly, an adhesive-free zone 91, which extends somewhat beyond the edge of the access opening 35, is present in the region of the access opening 35 The aim is to prevent the penetration of adhesive or adhesive vapors into the inner pack 12 in this way, in order to protect the pack contents. Glue points 34 for the permanent adhesive bonding of the closure label 42 to the inner side of the lid front wall 25 are provided on an upper side of the closure label 42 facing towards the outer pack 13 in the region of the third zone 41, so that the closure label 42 is also opened or closed by the actuation of the lid 15.

[0064] The blank (FIG. 2) for the inner pack 12 is designed in a particular manner.

[0065] In the first illustrative embodiment according to FIGS. 1 to 6, the inner rear wall 39 extends uninterrupted over the full extent or height of the inner pack 12. The inner front wall 36 is divided more or less centrally. A first, upper part wall 46 is connected to the inner end wall 37. A second, lower part wall 47 adjoins an inner bottom wall 48. In the finished inner pack 12, the part walls 46, 47 combine together to form the inner front wall 36 in the region of a transverse parting line 49.

[0066] The blank 33 of the inner pack 12 has inner lateral tabs, which cover one another and are connected to one another by adhesive bonding in order to form inner lateral walls 50.

[0067] The inner rear wall 39 is provided for its full height with continuous integral rear lateral tabs 51. External lateral tabs of the inner front wall 36 are likewise divided in the region of the inner lateral walls 50 and, as a consequence, form part lateral tabs 52, 53, which in the case of the folded inner pack 12 form the external surface of the inner lateral walls 50 in continuation of the parting line 49. The continuous, internally located rear lateral tabs 51 assure the stability of the inner pack 12.

[0068] Corner tabs, in particular inner bottom corner tabs 54 for positioning on the inner side of the inner bottom wall 48, arranged on the rear lateral tabs 51.

[0069] End corner tabs 55 are designed in a particular manner, in particular with a triangular shape or a V-shaped design. The end corner tabs 55 are arranged to either side of the inner end wall 37 and are connected to the latter by means of a fold line. The end corner tabs 55 are separated by punching cuts in relation to the rear lateral tabs 51 and the part lateral tabs 53 to either side of the upper part wall 46 of the inner front wall 36.

[0070] In the depicted illustrative embodiment, the end corner tabs 55 extend in the transition to the inner end wall 37 initially for the same width as the inner end wall 37 and then converge in the form of a V. The depth of the end corner tabs 55 in this case corresponds to the depth of the rear lateral tabs 51 and the part lateral tabs 53. A lateral edge 43 of the end corner tabs 55 is clearly oriented at an angle towards the principal axes of the blank 33, at an angle of slightly less than 45 thereto, whereas the other lateral edge 44 of the end corner tabs 55 is oriented at only a small angle to the transverse axis of the blank.

[0071] The part lateral tabs 53 to either side of the upper part wall 46 of the inner front wall 36 also have a special design and are provided with an inclined lateral edge 45, which, like the lateral edge 43 of the part lateral tabs 53, runs oriented at an angle of approximately less than 45 in relation to the principal axes of the blank 33. At the same time, the lateral edges 45 and the lateral edge 44 respectively of the end corner tabs 55 are arranged in this case adjoining one another on the same side of the blank 33. Because of the inclined lateral edge 45, the part lateral tabs 53 as a whole have a substantially trapezoidal design.

[0072] In the folded inner pack 12, the end corner tabs 55 make contact between the outer rear lateral tabs 51 and the inner part lateral tabs 53. Because of the above described shape of the part lateral tabs 53 and the end corner tabs 55, the visual impression of an envelope fold occurs in the upper region of the inner lateral walls 48 in each case, as can otherwise frequently be found in inner packs made of a foil material.

[0073] In order to prevent a rear gap from occurring, because of the end corner tabs 55, between the rear lateral tabs 51 and the part lateral tabs 53, deformation of the material of the part lateral tabs 53 formed by embossing is proposed as a further special feature, which is configured outside the region of contact of the end corner tabs 55 with the part lateral tabs 53, in particular along the lateral edge 45. This is provided with an embossing region 56 in the section which protrudes beyond the end corner tabs 55. In the embossing region 56, the part lateral tab 53 is deformed in such a way that it bears against the rear lateral tab 51, and the formation of a gap between these two parts is thus prevented. The two parts are connected to one another by an appropriately positioned glue point 57. The embossing region 56 extends as far as the free end of the lateral edge 45. The inner rear lateral tabs 51 and the part lateral tabs 52, 53 are connected to one another by adhesive bonding, for example by glue points or a glue strip 86, outside the region of the envelope-like folding.

[0074] The inner bottom corner tabs 54 are generally of rectangular configuration, as in the prior art. This also applies to the rear lateral tabs 51 and the part lateral tabs 52. Consequently, the visual impression of an envelope fold is created in the region of the inner lateral walls 50 only in the upper part of the inner pack 12, which protrudes from the box part 14. The inner lateral walls 50 are of conventional design in the lower part of the inner pack 12.

[0075] A further special feature relates to a tab 31 for the connection of the two part walls 46, 47 of the inner front wall 36. The tab 31 is arranged in extension of the lower part wall 47 and is connected by adhesive bonding to the upper part wall 45, preferably by a row of glue points 32.

[0076] The inner pack 12 fills the outer pack 13 completely. In addition, the inner pack 12 can be secured in the outer pack 13 with glue 88. The access opening 35 is positioned so that the access opening 35 is freely accessible with the lid 15 of the outer pack 13 opened. The outer pack 13 is designed as a tab box without collars.

[0077] The second illustrative embodiment according to FIGS. 7 to 9 differs from the first illustrative embodiment described above by the construction of the part lateral tabs 53. An embossed zone 58, in which the end corner tabs 56 are accommodated, is present instead of an embossing region 56 along the lateral edge 45.

[0078] In the region of the embossed zone 58, the respective part lateral tabs 53 are deformed by embossing in such a way that a kind of pocket is formed, which corresponds to the respective end corner tabs 55 of the inner pack 12 with regard to its dimensions and position. The part lateral tabs 53 are consequently deformed outwards in the region of the zone 58.

[0079] The third illustrative embodiment according to FIGS. 10 to 12 differs from the first illustrative embodiment described above likewise by the construction of the part lateral tabs 53. An embossed zone 59 finds an application here, as in the second illustrative embodiment, albeit being arranged in the region of the rear lateral tabs 51, corresponding to the respective position of the end corner tabs 55 on the inner pack 12. The rear lateral tabs 51 are consequently deformed inwards, in order to form a pocket for the end corner tabs 55.

[0080] The third illustrative embodiment further depicts a variant of the closure label 42. This is continuous on the underside, that is to say is also provided with adhesive in the region of the access opening 35. In order to prevent the pack contents from being compromised by the adhesive, a cover 85, for example made of silver foil, is positioned in the region of the access opening 35. The cover 85 extends circumferentially somewhat beyond the access opening 35, so that an overlap region is created (FIG. 11).

[0081] The blank 33 is also slightly modified, in particular in the sense that the inner front wall 36 is designed integrally. The tab 31 is accordingly arranged at the end of the inner bottom wall 48 and is connected to the inner front wall 36. Because of the modified construction of the blank, the outer lateral tabs of the inner lateral walls 50 are also no longer formed from part lateral tabs 52, 53, but in addition only from the (extended) lateral tabs 53.

[0082] It will be appreciated that both of the last-mentioned modifications of the blank 33 are also capable in principle of finding an application in the first two illustrative embodiments.

[0083] The production of the packs 10 described above is represented by way of example in FIGS. 13 to 16. Of these, FIGS. 13 and 14 initially depict the production of the inner pack 12. FIG. 15 depicts the positioning of the closure labels, and FIG. 16 depicts the production of the outer pack 13.

[0084] The sequence of the important folding steps, which are necessary in order to fold an inner pack 12 from the blank 33, is represented initially in FIG. 13. The unfolded blanks 33 are accordingly brought into a first intermediate folded position, in particular by the erection of the rear lateral tabs 51, the inner end wall 36 and the lower part wall 47 of the inner front wall 36. The inner bottom corner tabs 54 are also folded, and the group of cigarettes 11 is supplied. In the following step, the part wall 47 is folded onto the group of cigarettes 11, and the inner end wall 37 and the upper part wall 46 of the inner front wall 36 are erected. The upper part wall 46 as well as the lower part wall 47 are then folded onto the group of cigarettes 11. The end corner tabs 55 are subsequently folded, and the part lateral tabs 52, 53 are then folded into the plane of the inner side walls 50.

[0085] FIG. 14 depicts an appropriate folding turret 60 for the implementation of the steps described above.

[0086] The folding turret 60 has pockets 61 evenly distributed over the circumference thereof. Stamping the blanks 33 is accompanied in every case by the formation of the intermediate folded position. A guide 62 extending along the circumference serves to support the upper part wall 46 of the inner front wall 36 during the feeding of the group of cigarettes 11 and during the application of glue points 32 positioned on the circumference of the folding turret 60 by means of a glue nozzle 63. Folding around the inner end wall 37 and the part wall 46 is effected by means of an active folding device 64 and a subsequent folding switch point 65. Guides 66, 67 are also used for guiding and folding back the lower part wall 47.

[0087] The folding method or the individual steps described thus far need to be modified slightly for an inner pack 12 according to the third illustrative embodiment, in which the inner front wall 36 is designed integrally. The folding procedure then corresponds substantially to the folding procedure for a conventional hinge/lid pack (tab box).

[0088] In an ejection station for the folding turret 60, fixed end tab folders 68, which take care of the folding back of the end corner tabs 55, are arranged in the conveying path of the inner pack 12.

[0089] In the course of the further transport of the partially finished inner packs 12 on a driving belt 69, the glue 86 (preferably hot-melt) is applied initially in the region of the inner lateral walls 50 by means of glue nozzles 70 arranged laterally next to the transport section, and the part lateral tabs 52, 53 are then folded down and the inner pack 12 closed.

[0090] The inner pack 12 is then pushed into a pocket of a rotating wheel 71 and is transferred to a push-off device 72a extending transversely in relation to the transport direction of the driving belt 69.

[0091] In the region of the push-off device 72, the inner packs 12 are conveyed along a downward-inclined sliding plate 73 by means of overlying driving belts 74. At the end of the sliding plate 73, the inner packs 12 are diverted into an upright conveyor section 75 and are transported continuously upwards at a preferably constant speed. At the same time, the inner packs 12 lie on an inner lateral wall 50, that is to say transversely to transport direction, so that the inner end wall 37 is exposed laterally, for the purpose of positioning of the closure labels 42.

[0092] The closure labels 42 are positioned on a continuous carrier strip 76, which is drawn from a corresponding label reel 77 by means of a drive roller 78, passes through a web edge control 79 and finally a compensating pendulum 80. The closure labels 42 are then peeled from the carrier strip in the region of a deflector 92 and are transferred to a suction roller 93, which delivers the closure labels 42 against the inner end walls 37 of the inner packs 12. The carrier strip 76 is wound onto a carrier strip reel 83.

[0093] The inner packs 12 next pass through a label folding station 81, in which the two legs of the closure labels 42 protruding laterally beyond the inner end walls 37 are positioned against the inner rear wall 39 and the inner front wall 36 of the inner packs 12. The label folding station 81 possesses a U-shaped folding device 82 for this purpose, which is moved appropriately against the inner pack 12. At the same time, the folding device 82 accompanies the inner packs 12 in the course of the application of the closure labels 42.

[0094] The inner packs 12 provided with the closure labels 42 are then fed to a further folding turret 84 and are packed there into the outer packs 13. The folding turret 84 is designed appropriately as a standard folding turret for tab boxes, but with the difference that the inner pack 12 replaces a cigarette block with collars. The only special feature is the provision of a glue nozzle 85 for applying the glue points 34 to the external surface of the closure labels 42 for connection to the inner side of the lid front wall 28 on a station of the folding turret 84. Subsequently to the folding turret 84, the finished folded packs 10 as far as the box lateral walls 22 are transferred to a driving belt 89. Glue 87 is applied in the customary manner by means of glue nozzles 90 in the region of the box lateral walls 22, and the box lateral tabs 20, 21 are connected to one another to produce box lateral walls 22.

[0095] Inner packs 12 and outer packs 13, of which the upright pack edges are designed identically so that the packs have a rectangular cross section, are depicted respectively in the depicted illustrative embodiments. Beveled or rounded pack edges are also conceivable, of course. Packs which have differently shaped pack edges, for example packs of which the upright pack edges in the region of the front side are shaped differently from the upright pack edges in the region of the rear side, are conceivable in addition. It is also conceivable for individual pack edges to be designed differently from other pack edges. It is further conceivable for the different pack edges to be combined with one another in any desired way.
